A married couple was lying in bed one night. The wife is all curled up, ready to go to sleep, as the husband turns his bed lamp on to read a book. As he's reading, he periodically reaches over to his wife, and fondles her "special area." He does this a few times, but only for very short intervals before turning back to read his book.
The wife gradually becomes more and more aroused... and, assuming that her husband is seeking some encouragement, she gets up and starts stripping right in front of him.
The husband is confused and asks, "Why are you taking off your clothes?" His wife replies, "You were rubbing me downtown.... I thought it was foreplay."
The husband says, "No, not at all." His wife asks angrily, "Well, then what the hell were you doing?" He says... "I was just wetting my fingers so I could turn the pages."
